WD45 transmission questions

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I'm rehabbing a neglected 1955 WD 45 and am suspicious that it's leaking hydraulic fluid past the seals into the transmission.  If that turns out to be the case, I'd like to postpone the seal replacement until a more opportune time and wonder how that might work.
How much overfill of the transmission is tolerable, especially if one fills the transmission, differential, and hydraulic reservoir with hytran throughout?  Leaking in new places would be expected, and it'd be great if the hytran can seek a level high enough for the pump to run until the proper fix can be done.  Have any of y'all given this a try in the WD 45?

	As MACK used to say: "if HyTran is good enough for a new 600 HP tractor, why would it not be OK in a WD-45 ??" I've used HyTran type oil in my WD-45 for 12 yrs now. No issues. Edited by DrAllis - 2 hours 34 minutes ago at 8:02pm
